My grand daughter is 7 and always ready to have her photo taken. I believe that all girls under the age of 10 are the same. Once they start approaching teenage years, though, their willingness decreases. By the time they are adult females, I think that 99% of them avoid the lens end of cameras like the plague.

And then, when you do convince them to pose , or even be in a group shot, they invariably say that we did not capture them well.

Here is to the beauty of women everywhere, even if it is impossible to please them with our little works of art.
